[Next] Frame transform scale not accounted for

[chrisvxd]

Description

When dragging an item in a scaled iframe, the droppable shape moves by more than the sensor. This implies the scale transform is not being accounted for.

I was able to reproduce this in the Puck demo app, but not in the dnd-kit iframe stories. Since I was unable to reproduce this in the iframe stories, it could be a Puck issue.

Possibly related: #1704.

Environment

• dnd-kit version: 0.1.13

Steps to reproduce

Currently unable to reproduce in Storybook, but able to reproduce in the Puck demo app.

1. Pull this branch: Add Puck example app #1677
2. Update deps
3. Run bun dev
4. Visit http://localhost:5173/
5. Drag in a new item

What happens

The droppable shape moves more than the pointer sensor once in the scaled iframe.

What I expect to happen

The droppable shape to follow the pointer sensor

Possibly fixed by a97b10c, have not tested yet

@chrisvxd can you confirm if this is still an issue?

[chrisvxd]

@clauderic I was also hoping for that fix to help, but alas it does not help. I tested in the Puck demo app and Puck repo environments.

Additionally, latest build results in a new error #1710.

[clauderic]

Thanks, will investigate!

#1710 should be resolved in 0.1.15

[clauderic]

Should be solved by 0f68bb6

Awesome, appears fixed in the demo app! Thanks @clauderic!
